https://kevinbinz.com/2019/02/17/domestication/ https://kevinbinz.com/2019/02/17/domestication/ - this article points out the "mild neurocristopathy hypothesis" to explain gradual removal of aggression during domestication. "domestication syndrome is a byproduct of changes to the NCC migration pattern" in the development of the neural crest. In this scenario, Seratonin inhibits the Negative Valence System, in turn giving domesticated hominids a longer window of time to collect social information to determine how to apply aggression towards other animals. NCC migration patterns are also suspected to change facial characteristics, part of neural crest development, that are observed in domesticated animals: hair, ears, mouth, teeth, etc.
